Fruit flies share 75% of the genes that cause diseases with humans, so scientists can learn about human genetics by studying fruit fly genetics.
Answer:
The ancestor of these organisms lived on a landmass long ago that included Madagascar, India, and Australia.
Explanation:
The three, Madagascar, India and Australia were found together on a piece of land called Gondwana, which were part of the continent called Pangea, approximately 300 million years ago. Gondwana began its separation at the beginning of the Jurassic. Meanwhile, South America began to separate to the west. On the other hand, East Gondwana, which was made up of Antarctica, Madagascar, India and Australia, began its separation from Africa.
Answer:
Adenine on one strand can pair only with thymine on the other strand; cytosine, only with guanine.
Explanation:
DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.
Plants use carbon to live, just like humans use oxygen. It's a virtuous cycle sine humans breathe oxygen and expel carbon, and plants "breathe" carbon and expel oxygen.
If plants weren't there to "breathe" the carbon, it would just sit in the world, and build up in the atmosphere.
Answer:
The most likely cause of Nota’s pain is shoulder dislocation/ subluxation.
Explanation:
When Laika picked Nota up by the right arm and lifts him, the shoulder was in abduction and external rotation, which favours shoulder dislocation. This was supported by the loud popping sound, guarding of right arm and pain, which is severe in nature.
